Playground - retrieving pages from play-cache

by PBKResearch

I have a mystery when using the 'Play Pages' button on the top right of the playground. One particular file, which has been through several versions, never appears in the drop-down list on clicking this button. It is in the play-cache, and I access it by opening the file from the file explorer with WordPad, then copying and pasting into the playground. More mysteriously, having got at in this way, as a test I closed the playground containing it, then clicked the 'Play Pages' button in a new empty playground; the mystery file was there at the top of the list. Close down Pharo and restart, click 'Play Pages' in a new playground, the file is missing again. Is there anything I should be doing to ensure it is accessible? I have tried closing the playground before I shut down Pharo, and alternatively leaving it open and letting the Pharo shut-down close it. Does 'Play Pages' work by examining the contents of the 'play-cache' folder, or does it maintain its own list of files? I am using 32-bit Moose Suite 6.1 (Pharo 6.0 Latest update: #60541) on Windows 10. Many thanks for any help Peter Kenny

The discussion so far shows that CoC is not a distraction to many and the ones who think so, should be leading by not being distracted with long threads and emails, and also showing how to start and continue the discussions and projects on the topics they care about here and in the repositories. I, for example, have a concern about data and privacy and the way it influences our vision and shape of the world. Maybe we can share some interest and projects on that front. Here, we don't have proper seasons, but I wish everyone interesting and insightful times where ever you are. Cheers, Offray

Ah, I recently condensed the changes file of the Squeak version, so the first download is much faster. I also think the Pharo 6 image I was using is much larger than the Squeak one, for some reason. I intend to update the Pharo image to version 8 soon, anyway. > By the way, I'm using Firefox on Ubuntu, so what do I type to get, for > example, "print it"? Ctrl-P is captured by Firefox. You should be able to use the normal meta key for your host platform, it's a bug in the supporting page code in .../js/squeakjs/squeak.js if not. We can handle command key events ourselves and then call .preventDefault() on them, to keep the web browser from chiming in. It should be that Smalltalk handles all of them except for copy/cut/paste/reload.

Thank you Craig Latta. I see there is a caffeine.js.org/pharo "This page is an early demo of running Pharo 6 with the SqueakJS virtual machine. It gets far enough now that I think several people in the Pharo community could fix the rest of the bugs (mostly missing primitives).

Re: [Pharo-users] Code of Conduct

by Jerry Kott

Justâ¦ WOW. Iâve been fighting the urge to add my two cents to the discussion, but didnât feel âqualifiedâ - Iâve been just lurking here, both on the mailing list and this topic. I havenât contributed to Pharo (yet), but any discussion that involves freedom of expression (which this is I believe) naturally piques my interest. I only read the Code of Conduct version as of today, and while on surface itâs not that controversial (any longer), if I had any say in the subject, I would vote against any form or shape of it. Many have expressed their reasons, here are just some of mine: The wording can change at any time (as we have seen over last couple of weeks), without any real accountability of the CoC authors/editors to the community. That alone should be a red flag. I have a somewhat remotely related example of that: In 1948, a single added sentence in the Constitution of my country changed it from a fledgling democracy to a brutal dictatorship that lasted forty years. âFoundational documentsâ are extremely difficult to get right - whatever ârightâ means. Almost every CoC I have seen in recent times, in communities online and in the real world, reminds me this: https://en.wikipedia.org/wiki/Moral_Code_of_the_Builder_of_Communism <https://en.wikipedia.org/wiki/Moral_Code_of_the_Builder_of_Communism> . Read the twelve rules. Shivers run up my spine when I see the similarities between that and modern Code of Conduct wordings. This was displayed in schools and other public building when I was growing up. Nobody I knew followed it, but it could be used arbitrarily to mark people as âenemiesâ and discriminate against them - the very antithesis of tolerance and inclusivity. (I repeat what others said) This is a predominantly technical forum, albeit with some creative aspects. I borrow a phrase here: âAny good idea withstands scrutinyâ. Knowing that should be enough of an incentive to be thoughtful and respectful. That doesnât mean you canât fight for your idea (on the contrary), and fighting sometimes requires some strong words. Get over it. Lifeâs not âeasyâ, âsafeâ, or âfairâ. I donât see a problem on this list (or even in the wider Pharo/Smalltalk community) that needs solving or gets solved by a CoC. Why waste our energy on something that is not a problem? If everything else got half of attention as this topic, wouldnât that be awesome? Ultimately this is about human behviour, and as we know, thatâs always the hardest thing to change/influence in any field. Speaking of which: How is that security stuff coming along, Pharo community? Two years in the row my ESUG presentations included screenshots of a Pharo-backed web site, pointing out how insecure the site is. Details have been blurred to protect the site, but anyone who does Pharo/Seaside work should be alerted if they paid attention. I know that the maintainers of the site were in the audience, and I am amazed that they have not checked their site to see if they have some work to do to address the vulnerabilities. Note: this is not unique to Pharo. Itâs a simple change in behaviour that should have happened, but it has not. The point here is: as a community, Pharo (and other Smalltalk groups) has a lot of work to do. Code of Conduct is an unnecessary and wasteful distraction. In the meantime, I see no discussions here about how are we going to address the world-wide crisis of Privacy Erosion, or how to establish ethical coding best practices. How can we ensure that information collected as a result of our work remains confidential and secure where needed, and is used ethically for the betterment of the planet and the human race? I don't give a ratâs ass about following a community Code of Conduct if it silences what I or others have to say in public, while our most private, personal data is harvested left and right by unscrupulous geeks in Silicon Valley and elsewhere. Thatâs a problem we should be trying to solve. There. Stepping down from the soap box. Happy Autumnal Equinox, everyone! Jerry Kott This message has been digitally signed.

Can one use freetype fonts with Roassal?

by Mark Miller

I'm interested in using Pharo to do a math presentation, by which I mean I'd like to show some algebra in process. I'm using a Mac (macOS Mojave), and Pharo 7. I've settled upon Roassal2 as a good package to use for this, as I'd like to arrange characters, and possibly do a little animation, and maybe a little bit of effects with alpha settings. However, I'd like to show the alphabetic characters in the traditional way for math (italicized), and I'd like to be able to control the font size. Looking at the Roassal examples, I can see how to control the font size, but not the font face. I've been exploring what package Roassal uses for displaying fonts. It appears to be FreeType. I have FreeType installed on macOS from Homebrew, and I've copied a couple fonts into a "fonts" folder under my home directory (as FreeType in Pharo seems to demand)--Times New Roman Italic, and Arial Italic--but if I try to change the font face to any one of these, the font face doesn't change, but I lose font sizing. Every character appears the same size, even though the code is still trying to set the font height. I'll use the Roassal exampleFontSize example to illustrate. As-is, exampleFontSize displays this: <http://forum.world.st/file/t26333/Roassal_fonts1.png> Once I try to change the font face to Times New Roman Italic, it looks like this: <http://forum.world.st/file/t26333/Roassal_fonts2.png> I've tried changing it to use Arial Italic, but the font face still doesn't change, and I lose all font sizing. Any ideas on why this is happening? Thanks. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Where did all the Comments Go?

by Paul DeBruicker

Hi Andrew- If you use the scripts from https://get.pharo.org (for 32 bit) or https://get.pharo.org/64 (for 64 bit) to download a vm+image e.g. curl https://get.pharo.org/64 | bash Do you also have the disappearing comments issue? I can't imagine it would make a difference and that you'll still see the problem but it would be a ten minute test at most. FWIW I can write and read class comments in Pharo 7 just fine, but don't use and never load SmaCC. Could it be a problem with SmaCC + Pharo7? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
